分形是一种具有自相似特性的现象、图象或者物理过程。每一组成部分都在特征上和整体相似,只仅仅是变小了一些而已。在海报设计和插画领域都有很多分形图形的应用,时常都会产生令人惊艳的效果。大部分人会用计算软件作出这些具有自相似性的逐渐缩小的图形,而我们这次则只使用Photoshop来做出这种效果。过程中会帮助大家更好地理解自由变换工具以及相关的几组快捷键的应用。 我们先来看看最终效果:
最终效果图 第一步: 新建一个空白文档,大小为1600×1200像素,足够大的画布让创作更为自由,而且之后用来作为壁纸也很方便。使用Ctrl R打开标尺,设置单位为百分比,这对之后的步骤非常重要。新建一条垂直和一条平行的参考线,交叉穿过画面的中心。接着使用渐变工具,选择径向渐变(颜色从#095261渐变到#000000)在画布上画出一个均匀的渐变效果,那么你应该得到一张如下图的文档。

第二布:
你现在需要画出这教程中唯一的一个图形——圆形,所有的东西都将从这个圆形开始。选择椭圆工具,按住SHIFT画出一个完美的圆形,你也可以按住ALT从中心开始画圆。这个圆形的半径约为83像素且以画布的中心为圆点。接下来在图层面板创建一个新组,命名为“Fractal”,把刚才做出的圆形图层移动到其中。

Enhance and retouching photos in Photoshop can be achieved by adjusting brightness and contrast, using the Repair Brush Tool. 1) Adjust brightness and contrast: Increase brightness and contrast to improve underexposed photos through the Image->Adjustments->Brightness/Contrast menu. 2) Use the Repair Brush Tool: Select HealingBrushTool in the toolbar and apply to remove miscellaneous points or scars in the image.

Photoshop can be obtained by purchasing a permanent license or subscribing to CreativeCloud. 1. Purchase a permanent license for long-term use, no monthly payment, but no latest updates are available. 2. Subscribe to CreativeCloud to access the latest version and other Adobe software, and you need to pay a monthly or annual fee. The choice should be based on frequency of use and requirements.

Photoshop is specialized in image editing, layering and masking, digital painting and a variety of design applications. 1) Image editing and repair: remove defects and adjust color and brightness. 2) Layers and masks: non-destructive editing and creation. 3) Digital paintings and illustrations: create art works. 4) Practical applications: graphic design, web design and digital art creation.

Photoshop is very practical and creative in practical applications. 1) It provides basic editing, repairing and synthesis functions, suitable for beginners and professionals. 2) Advanced features such as content recognition fill and layer style can improve image effects. 3) Mastering shortcut keys and optimizing layer structure can improve work efficiency.

Advanced features of Adobe Photoshop include advanced selection tools, layer blending modes, and actions and scripts. 1) Advanced selection tools such as the Quick Selection Tool and the Color Range Selection Tool can accurately select image areas. 2) Layer blending mode such as "overlapping" mode can create unique visual effects. 3) Actions and scripts can automate repetition of tasks and improve work efficiency.

Photoshop's powerful functions in photo editing and enhancement include: 1. Use the "Repair Brush Tool" to remove acne, 2. Use the "Liquefaction Tool" to slim face, 3. Use the "Frequency Separation" technology to accurately retouch images. These functions are implemented through algorithms and image processing technology to optimize image processing effects.

Key features of Photoshop include layers and masks, adjustment tools, filters and effects. 1. Layers and masks allow independent editing of image parts. 2. Adjust tools such as brightness/contrast can modify image tone and brightness. 3. Filters and effects can quickly add visual effects. Mastering these features can help creative professionals achieve their creative vision.

Photoshop's applications in digital art include painting, illustration and image synthesis. 1) Painting: Using brushes, pencils and mixing tools, the artist can create realistic effects. 2) Illustration: With vector and shape tools, artists can accurately draw complex graphics and add effects. 3) Synthesis: Using mask and layer blending mode, artists can seamlessly blend different image elements.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
